Wireless sensor network safety management system

Abstract

The present invention proposes a wireless sensor network security management system, which dynamically combines appropriate security services according to security service requirements and communication environments, so that the network is in a dynamic security state of different levels, and overcomes energy waste and insecurity caused by static security in security protection. Flexible; at the same time, the safety management system adopts a distributed structure, which overcomes the energy consumption problem caused by the communication between the base station and the node in the centralized system. The security management system is implemented with a cross-layer security management architecture. The architecture includes five components: security agent: obtain various parameter values ​​by interacting with each layer through defined interfaces; Security combination protocol; security protocol: activate the corresponding security protocol according to the security combination protocol; data component: store the security services that the security protocol can provide, and use it for security decision-making; resource library: store the cost parameters consumed when the security protocol is running.

Description

technical field [0001] The invention belongs to the field of network security technology and service computing, and relates to a security management system in a wireless sensor network, which uses security as a service and dynamically combines security services according to security service requirements and communication environments, thereby proposing an adaptive Wireless sensor network security management system. Background technique [0002] With the development of sensor network applications, its security issues have attracted more and more attention. Starting from the application of sensor networks, there are different security service requirements for different application requests. However, in the existing sensor networks, security measures are unified. Yes, that is, for different applications, the security protection provided by the network is the same and maintained at a static security level, which will result in: 1. Some applications may not require very high secu...
